The button head style reduces snag points in assemblies while maintaining a secure clamp load. Drive interface is Torx Plus IP27, which delivers improved torque transfer and reduced cam-out compared to standard hex socket drives. Thread specification is 1\/4-28 UNRF with a Class 3A fit, providing close tolerances suitable for vibration-prone environments. Black oxide coating offers mild corrosion resistance and a uniform matte appearance. Head height measures 0.0460 inches. Hardness rating is 39-44 HRC. Installed by machinists, maintenance technicians, and mechanical assemblers across a wide range of industrial and OEM applications.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in machine assemblies, sheet metal panels, brackets, and enclosures where a flush or low-profile fastener head is required. The 1\/4-28 fine thread pitch provides strong thread engagement in thin-wall or tapped-hole applications. Alloy steel construction and a 39-44 HRC hardness rating make this screw appropriate for structural and load-bearing joints in both light industrial and precision mechanical settings. The Torx Plus drive requires an IP27 or TP27 driver bit, which should be confirmed before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eButton head profile minimizes protrusion and reduces snagging in close-clearance assemblies\u003c\/li\u003e\n  \u003cli\u003eTorx Plus IP27 drive reduces cam-out and improves torque transfer over standard hex socket\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNRF fine thread with Class 3A fit for tight tolerance and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eAlloy steel at 39-44 HRC for high tensile strength and durability\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion resistance and a matte finish\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank along the 3\/4-inch length under head\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-28 UNRF Class 3A button socket cap screw suitable for tapped holes and threaded inserts conforming to ANSI\/ASME B18.3 and ASTM F835 specifications in general industrial and OEM mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or mechanical technician using a calibrated IP27 or TP27 Torx Plus driver bit. Confirm thread engagement depth and tapped-hole condition before driving. Do not exceed the rated hardness class when pairing with mating threads; using this screw in soft or dissimilar materials may cause thread stripping. Refer to applicable ANSI\/ASME torque guidelines for 1\/4-28 alloy steel fasteners when setting final clamp load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNRF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 3A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.0460 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Torx Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorx Drive Size\u003c\/strong\u003e: IP27 \/ TP27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 39-44 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI\/ASME B18.3, ASTM F835\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 353-2412-01\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720570634546,"sku":"353-2412-01","price":2645.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b68dfc9ed774fb6ba15b5cd6d6e0036_338c1fc0-5f2b-4565-aec9-069eac372f80.jpg?v=1788566241","url":"https:\/\/voomisupply.com\/products\/value-collection-353-2412-01-button-cap-screw-1-4-28","provider":"Voomi Supply","version":"1.0","type":"link"}
